If Valhalla last year was "dreadful", then I can only imagine with wonderment about what it must have been like in 2000, because I rode it last August and while I personally found the level of wetness a bit too much, and I also found sitting in a small pool of water for the entire ride mildly uncomfortable, some of the effects were incredibly impressive!
I must admit, I don't think Valhalla is anywhere near my favourite water ride for the aforementioned reasons, but as a dark ride, I thought it was quite impressive!
